We use 3 different coatings at work. They go from soft to hard. I can get you the info later. The boards range from commerical to military boards. Analog and RF. Not sure how much work you want to put into getting it off vice protection of the coating. If you are thinking about potting we have options for that too.

If you want protected connectors I would look at AMP connectors, cost more but worth it, instead of the standard DB25 connector. Non-conductive grease may work but it can be messy and needs to be replaced every now and then.
